Answer:

b

Step-by-step explanation:

Based on the equation in the question , the R2 would be 0.934.

To compute R2, we need to use the formula:

R2 = SSR / SST

Given that SSR = 14,141.7 and

SST = 15,128.4,

We can substitute these values into the formula:

R2 = 14,141.7 / 15,128.4

R2 ≈ 0.934

b. To compute Ra2, we need to subtract R2 from 1:

Ra2 = 1 - R2

Substituting the value of R2 we calculated in part a:

Ra2 ≈ 1 - 0.934

Ra2 ≈ 0.066

c. A large R2 value indicates that the estimated regression equation explains a large amount of the variability in the data.

In this case, R2 is approximately 0.934, which means that the estimated regression equation explains about 93.4% of the variability in the data.

So, the answer is "Yes".

The correct option is (b) sample size.

In the formula for calculating the standard deviation, the letter n represent  sample size.

What is standard deviation?

Standard deviation is a statistical standard measure in finance that, when applied to an investment's annual rate of return, sheds light on its historical volatility.

Some key features regarding the standard deviation are-

A square root of a value deduced from correlating data points to a population's collective mean is used to calculate standard deviation. The formula is:

Standard Deviation = \(\sqrt{\frac{summation n to i=1 (x_{i}-bar x )}{n-1} }\)

Where,

\(x_{i}\)= value of the i th point the the given data set.

\(barx\)= mean value

n = total number of data points.

Thus, the standard deviation, on the other hand, determines all ambiguity as risk, even when it is in the investor's favor, like above-average returns.

Side AB is the longest length because m∠C > m∠B > m∠A for this AB > AC > BC option (D) AB is correct.

In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

It is given that,

Maries has a garden in the shape of a triangle ABC, for which m∠A = 51 degrees.

As we know, when two lines or rays converge at the same point, the measurement between them is called an "Angle."

From the figure,

m∠C > m∠B > m∠A

AB > AC > BC

Angle is the same for both ladders, the distance of the base of the longer ladder from the wall must increase proportionally.

In order to answer this question, we must consider the angle of the original ladder and the difference in length between the two ladders. The original ladder of 7 feet was placed at a distance of 4 feet from the wall, so the angle formed by the ladder and the wall was approximately 53°. To maintain the same angle with the longer ladder of 10 feet, the distance of the base of the ladder from the wall must increase by approximately 3 feet, so it should be placed at a distance of 7 feet from the wall. This is true because the angle formed with the longer ladder will be the same as the one formed by the shorter ladder due to the similar proportions of the sides of both triangles. To solve the problem, we must use the tangent formula to measure the angle formed by the ladder and the wall. This is done by dividing the opposite side (height of the ladder) by the adjacent side (distance of the ladder from the wall) to determine the angle. Since the angle is the same for both ladders, the distance of the base of the longer ladder from the wall must increase proportionally.

The speed of the star as compared to the speed of the star relative to earth is the frequency of light emitted by the source.

A star moving away from the observer (say on Earth) will have its emitted light red-shifted (move to lower frequency), i.e., the spectrum moving to left if we consider the intensity of light is plotted as a function of frequency with the frequency increasing from left to right.

A star moving towards the observer (say on Earth) will have its emitted light blue-shifted (move to higher frequency), i.e., the spectrum moving to the right if we consider the intensity of light is plotted as a function of frequency with the frequency increasing from left to right.

A star moving perpendicular to the observer (say on Earth) will have its emitted light will no change with respect to the spectrum of the stationary star.

These are due to the Doppler effect, the equation of frequency detected by the observer as

\(f_{0} = f_{s}\sqrt{\frac{1-\beta }{1+\beta } }\) where \(\beta = \frac{v}{c}\), v the relative velocity of the moving source (the star here), f^s is the frequency of light emitted by the source.

Hence the answer is the speed of the star as compared to the speed of the star relative to earth is the frequency of light emitted by the source.

The cost per second to power such a circuit during the peak usage period is approximately \(2.376 x 10^-6\)$/s. The cost per second to power the circuit during the peak usage period can be calculated using the following steps:

Calculate the power consumption of the device-The power consumption of the device can be calculated using the formula: Power = Voltage x Current. P = V x I, Substituting the given values:

P = 110V x 0.12A

= 13.2 W

Calculate the cost per second-The cost per second can be calculated using the formula:

Cost per second = Power x Cost per Joule

C = P x CC

= 13.2 W x 1.8 x \(10^-7\) $/J

≈ 2.376 x 10^-6 $/s

Therefore, the cost per second to power such a circuit during the peak usage period is approximately 2.376 x\(10^-6\) $/s.

Answer:

c) 20/11

Step-by-step explanation:

Given problem,

→ (11/12) × (240/121)

Then required product will be,

→ (11/12) × (240/121)

→ (11 × 240)/(12 × 121)

The total cost of haircuts for Michael's three children, including tip, would be $207.00.

If Michael gave a 20% tip and the haircuts cost $57.50, the tip would be:

Tip = 0.20 * $57.50 = $11.50

The total cost of the haircuts, including the tip, is as follows:

Total cost = haircut cost + tip

The total cost is $57.50 + $11.50.

The total cost is $69.00.

Since Michael took his three children to get haircuts, the total cost for all three children, including tip, would be:

Total cost for three children = three times the total cost

Total cost for three children = three times $69.00

The total cost for three children is $207.00.

As a result, the total cost of haircuts for Michael's three children, including tip, would be $207.00.

Answer:

\(y=0.2*4^{x}\)

Step-by-step explanation:

Notice when x increases 1, y is 4 times the previous one, so

the function is like \(y=C*4^{x}\)

To determine the constant C, put any pair of (x, y)

Use x = 0, y = 0.2, so

0.2 = \(C*4^{0}\) = C * 1 = C

then \(y=0.2*4^{x}\)

Answer:

\(y=(0.2)4^x\)

Step-by-step explanation:

General form of the exponential function: \(y=ab^x\)

Substituting the first point (0, 0.2) into the function:

\(\implies 0.2=ab^0\)

As any number to the zero power always gives one, \(b^0=1\)

\(\implies0.2=a \times 1\)

\(\implies a=0.2\)

Therefore, \(y=(0.2)b^x\)

Substituting the second point (1, 1.8) into the function:

\(\implies0.8=(0.2)b^1\)

\(\implies0.8=(0.2)b\)

\(\implies b=\frac{0.8}{0.2}\)

\(\implies b=4\)

So the final exponential equation is:

\(y=(0.2)4^x\)

Checking the equation with the remaining two points:

\(x=2 \implies (0.2)4^2=3.2 \ \ \ \checkmark\)

\(x=3 \implies (0.2)4^3=12.8 \ \ \ \checkmark\)

Hello! To calculate the slope we have to use the formula below:

Considering (x1, y1) = (-6, 6) and (x2, y2) = (5, 6), we have to replace it in the formula:

As the slope is 0, the line will not vary (will keep constant).

Answer:

58 in ^2

Step-by-step explanation:

Triangle on top   area = 1/2 base * height = 1/2 * 6 * 3 = 9 in^2

Triangle on bottom   = 1/2 base * height = 1/2 * 8 * 6 = 24 in^2

For trapezoid in the middle area = 1/2 ( 4+6)*5 = 25 in^2

Sum = 58 in^2

The slope between the points is same, hence the points lie on the same line. The point (2, 3) does not lie on the graph of y = 3x - 4.

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

Any two different points on a line can be used to calculate the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula.

The given points are, (1,3) (4,2) (-2,4):

Calculate the slope of the line formed by the points.

The slope of the line is given by:

m = (y2 - y1)/(x2 - x1)

For (1,3) (4,2):

m = (2 - 3) / (4 - 1) = -1/3

For (4,2) (-2,4):

m = (4 - 2) / (-2 - 4) = 2/ -6 = -1/3

The slope between the points is same, hence the points lie on the same line.

The equation of the graph is:

y = 3x - 4

The given point is (2, 3):

Substituting the point in the equation:

3 = 3(2) - 4

3 = 6 - 4

3 = 2

False.

Hence, the point (2, 3) does not lie on the graph of y = 3x - 4.
